Glun%/PPS 生物基复合材料。
（2）Glu 的引入提高了 PBS-co-Glun%共聚酯
的亲水性，未改变 PBS 的晶型，使得 PBS-co-Glun%
共聚酯与 PPS 共混相容性提高，从复合材料的
FTIR、XRD 和 SEM 结果可进一步验证此结论。
（3）随 Glu 含量的增加，PBS-co-Glun%/PPS
复合材料的断裂伸长率、酶降解率和光透过率均有
所增加；当 Glu 含量为 4%时，PBS-co-Glu4%/PPS
复合材料断裂伸长率达到最大值 98%；与 PBS/PPS

复合材料相比，PBS-co-Glu5%/PPS 复合材料酶降解
a — PBS/PPS; b — PBS-co-Glu1%/PPS; c — PBS-co-Glu2%/PPS;
d—PBS-co-Glu3%/PPS; e—PBS-co-Glu4%/PPS; f—PBS-co-Glu5%/PPS 率从 PBS/PPS 复合材料的 36.80%提高到 42.79%；
